invention is to provide 5 a rigid mounting for rock drills which will stand firmly under the heavy vibrations set during the operation of drilling.

Another object is to provide a-drill mounting which can be quickly and easily setup '10 in a pluralityof positions and which is adapted to permit the drilling of holes of any slant or inclination.

Another object is to construct a drill mounting which will permit of the ready transportation 7 of the drill and mounting from place to place.

Other objects will be in part obvious and in part pointed out hereinafter. p

All of these objects are obtained bythe mechanism shown in the accompanying drawings, in which Figure 1 is a longitudinal front elevation of the mounting and the rock drill set up in a position to drill vertical holes; 1

Figure 8 is a side View ofthe mounting and rock drill showing the position ofthemounting when .drillingholes close to the floor of a mine shaft or tunnel, and v Figure 9 is a view similar to Figure '8 show.- ing the rock drillonthe mounting advanced to its forwardmost position. Referring more particularly to thedrawin'g's, a frame 10 is-formed of :tVVD channel of the beams -12 and 14 secured together in parallel positions. At the top the channel beams 12 and 14are fastened :toa yoke 16 by means of bolts 18. Wing pieces 20 on the yoke16 support thelshaft 22 .on which is mounted a telescopic leg 24. The shaft 22 permits the leg 24 to be swung in any position in the plane perpendicular to the :shaft'22. A rod26 slides in the interior of the leg 24 and is secured in any desired position by: means of a set screw 28 in a collar 30 on the leg 24.

At the bottom the channel beams are held together by a plate32 bolted .to angle irons :34

in any suitable manner. Gusset plates86 and 38 riveted to the channel beams 12 and-14 respectively provide a mounting for sockets 40 and 42. These sockets are bolted to the gusset plates by bolts 44 and have apertures 46 and 48 through which legs 50 and 52aare .passed when the mounting is in the position shown in Figure 1. The legs 50 and 52 are held securely in place by set screws 54 and 56 and are pointed at the ends to secure .a firm footing on the rock floor '58. A second set of sockets 60 and 62 permit the legs 50 and 52 to be inserted when the mounting is set up in the position shown in Figures 8 and 9 and set Sorews64 and 66' secure the legs firmly in this position. I a

A shaft v68 passing through the channel beams at a position near the top in Figure 1 p-rovides'a mounting for a pulley 7 0 and a shaft 72 at a point near the bottom of the channel beams mounted in the plate 32 forms an axle for a pulley '74. i

Guides 76 and 78 secured to the channel beams in any suitable manner are adapted to receive theguideways .(not shown) of a rock drill 80 of a standard make. The rock drill shell .82 is provided'at its rearward end with i .of the :drill steel Thegu-ide 80;.consists essentially of two yokepieces 92 and=94 pivoted at 96 and98 by means ofish afts bolted to j the channel beams at 100 and 102. The two yoke pieces 92 and 94 are locked together by a iu-fshaped bar 104 which passes through the okeiece 94 and has its end burred'or exilarged as at 106 to prevent the accidental removal of the piece. The other end 108 passes over the yoke piece 92 as at 110 thus locking the two yoke pieces firmly together. vVhen it is desired to remove the drill steel it is onlynecessary to draw up on the bar 104 and swing the yoke pieces apart on pivots 96 and 98. y

In order to permit the drill to be withdrawn from the work a winch designated generally by 112 is secured to the channel beams by means of bolts 114' passing through a plate 116 which forms a base for the winch.

Frame pieces 118 and 120 provide means for mounting the various parts of the winch. An

. axle 122 passes through the frame pieces 118 and 120 and wheels 124 and 126 are mounted on the axle. A gear 128 keyed to the axle 122 meshes with a gear 130 keyed to an axle 132 mounted in the frame pieces 118 and 120 at 134 and 136. 41 gear 138 keyed to the other end of the shaft 132 meshes with a gear 140 mounted on a shaft 142 1which in turn is,

mounted in the frame pieces 118 and 120. A

winch drum 144 is keyed to the shaft 142 by means of a key 146. To the opposite end of the drum a ratchet wheel 148is secured by means of bolts 150. On avwing or extension 152 of the frame piece 120 a lever operated pawl 154 controlled by the, handle 156is mounted. A' spring 158 secured to the lever arm 156 and the frame piece 120 is adapted to hold the pawl'l54 in or out of operative position. V A brake drum 160 is rigidly mounted on the shaft 122 and abrake band 162operated by a lever 164 controls the rotation of the shaft 122. The lever 164 is pivoted at 166;

Attached to one of thewheels in this instance 126 isa crank handle 168 by means of which the winch is operated by hand.

lVhen the drill is in operation in the positions shown'in Figures 1 and 2'it is necessary to have a means of hoisting the drill 80 and a means of prohibiting the too, rapid clownward movement of the drilhwhich rapid comprised of the gears 130, 138 and 140 in I motion. Since the winchdrum' 144 is rigidly secured to the same shaft as the gear 140 the drum is revolved thus wihding up the rope 170. The drum 144 is locked in place by the pawl 154 acting on the teeth of the ratchet ring 148. When it is desired to set the drill in operation again the pawl is raised by means of. lever @156 and the weight of the rock drill is sufiicient to urge the drill steel 86 downward as the rock is cut away by the drill steel under the impact of the hammer piston (not shown). The amount of weight which the rock drill places on the drill steel 86 is controlled by the operator manipulating the lever 164 which tightens or loosens the brake band 162 on the brake drum 160.

The complete operation of the device is as follows: When it is desired to haul the mounting and rock drill to the work the wheels 124 and 126 are brought into contact with the ground byitilting the frame away from the horizontal position and the wheels then act as a carriage on which the mount ing and the drill may be moved from place to place. The mounti ngniay be set up from its traveling position to a vertical position as shown in Figures 1 and 2'by grasping the leg 24 and forcing the frame upward in much M the same manner that apike hole is used in raising a telegraph pole or flag staff.-

In order to operate the drill in the position shown in Figures 8 and 9 the leg 172 is inserted in the hole 174 in the yoke 16. The leg 17 2 is secured in place by a set screw 17 6. The drill now occupies a position under the frame and a rope 178 is passed from the winch drum 144 over the pulley 'to the pulley 72 as shown in dotted-lines in Figure 8. From the 'pulley 72 the rope is brought back to'the ring eye '84 in 'the shell of the rock drill. The drillmay now be advanced toward-therock wall 180 for the purpose of drilling a hole in the position shown at 182.

When the drill has advanced to the extreme position as shown in Figure 9 the rope178 is removed and passes directly from the winch drum to the pulleyv 7 O and is then hooked 7 wheel isto'be used for operating the winch,

the clutch member 123 is placed so" as to engage notches 127 inthe hub by means of the shoulder129formed on member 123. A pin 131 passing through clutch member 123 and the shaft 122 causes theshaft'122 to'rotate with the wheel to operate the Winch.

It will be seen from the foregoing description that this mounting permits the ready transportation of itself and the drill from placeto place and that it is capable of being easily set up in a plurality of positions for drilling operations, and thus the objects hereinbefore mentioned'are attained.
